Specific embodiment
It is described in detail below in conjunction with specific embodiment of the attached drawing to the embodiment of the present invention.It should be understood that this
Locate described specific embodiment and be merely to illustrate and explain the present invention embodiment, is not intended to restrict the invention embodiment.
Before introducing the specific technical solution of the present invention, the several concepts involved in the present invention arrived are first introduced：
Fig. 1 is block diagram provided by the invention, for file journalization carry module in the container of host's pusher side, the module
Including receiving unit 101 and processing unit 102, wherein for receiving carry information, which includes receiving unit 101
The configuration parameter of file journalization in the container, and the carry information is sent to the processing unit 102；Processing unit
102 for according to the configuration parameter on the host customized directory path, and by the file journalization in the container
Under the customized directory path on carry to the host.
Wherein, configuration parameter include file journalization in the container is mounted to required parameter on host, such as
It is mounted to space size, carry position etc. required on host, the configuration parameter in the present invention includes environmental variance, and processing is single
Member 102 for according to the environmental variance by the customized extension on file journalization carry to the host in the container
It carries under directory path.The setting of environmental variance is as follows：It, can be by being somebody's turn to do in container if there is file journalization to need to acquire in container
File journalization carry comes out, then needing to set for this document log in container, environmental variance is, for example,
KUBERNETES_LOG=/var/log/nginx, wherein KUBERNETES_LOG is environmental variance.Specifically, processing unit
102 can modify kubelet source code, and by modification kubelet source code, by environmental variance KUBERNETES_LOGS=/
Value indicated by var/log/nginx is mounted under the customized mount directory path on host, and/var/log/nginx is
Directory path of the file journalization in container.Wherein the major function of kubelet is exactly timing from somewhere acquisition node
The expectation state of pod/container (runs how what container, the copy amount of operation, network or storage configure
Deng), and corresponding container platform interface is called to reach this state.
Customized directory path includes：Fixation mount directory on host and non-under the fixed mount directory
Fixed mount directory；Wherein, on-fixed mount directory includes container group title and Container Name, and Container Name is container group title
Subdirectory.Customized mount directory path can be for example/var/log/filelog/deployment-name/pod-
name/container-name/.Here pod-name indicates container group title, and container-name indicates Container Name,
Deployment-name is the title of deployment.If log in container is mounted to host using existing carry technology
On machine, then the path being mounted on host is to write dead, in this case multiple pod operation of a deployment manually
It will cause multiple pod carry conflicts when on the same host.And the present invention is by way of modifying kubernetes,
File journalization in container is mounted under the customized mount directory path on host, customized mount directory path is for example
For/var/log/filelog/deployment-name/pod-name/container-name/, thus solve it is above-mentioned
Multiple pod are run on the same host leads to the problem of carry conflict.Wherein, fixed mount directory is /var/log/
Filelog/deployment-name/, on-fixed mount directory are /pod-name/container-name/.
In the case where receiving unit 101 receives carry information, processing unit 102 will be dynamic for pod and container
State distributes pod-name and container-name.Specifically, processing unit 102 includes environmental variance judgment sub-unit and extension
Subelements, the environmental variance judgment sub-unit, for judging whether the carry information includes the environmental variance, and will
Judging result is sent to the carry subelement；The carry subelement, for receiving above-mentioned judging result, and in the judgement
As a result it is when including the environmental variance, it will be described customized on the file journalization carry to the host in the container
Under directory path；In the case where the judging result is does not include the environmental variance, by the file journalization in the container
Under the directory path of the fixed mount directory on carry to the host.
With fix mount directory be /var/log/filelog/deployment-name/, on-fixed mount directory be/
For pod-name/container-name/, carry information will be received in receiving unit 101 and is sent to processing unit 102
Afterwards, the environmental variance judgment sub-unit of processing unit 102 judges the configuration of the file journalization in the container in the carry information
It whether include environmental variance KUBERNETES_LOG=/var/log/nginx in parameter, if the file journalization in container is matched
Setting includes environmental variance in parameter, then the carry subelement of processing unit 102 is by the file journalization carry in container to host
On customized directory path/var/log/filelog/deployment-name/pod-name/container-name/.
If in the configuration parameter of the file journalization in container not including environmental variance, the carry subelement of processing unit 102 will hold
For file journalization carry in device to directory path/var/log/filelog/deployment-name/, such case is existing
Situation in technology, such case are likely to cause under the fixation mount directory on host that there are multiple titles are the same
Pod, then the same pod of this multiple title will generate conflict on host.
Further, the processing unit includes the legal judgment sub-unit in path, and the legal judgment sub-unit in path is used for
The judging result that the environmental variance judgment sub-unit is sent is received, and being in the judging result includes that the environment becomes
When amount, judge whether the directory path of the file journalization identified in the environmental variance in the container is legal；If sentenced
Disconnected result be it is legal, then the carry information is sent to institute's carry subelement；If it is judged that exporting mistake then to be illegal
Accidentally.That is first have to judge whether directory path of the file journalization in container in container be legal before carry,
Carry just is carried out to this document log in container on host in the case where legal.Judge to be identified in environmental variance above
Directory path of the file journalization in container it is whether legal, mainly judge whether its format meets prescribed form, that is,
It says and is then judged as legal in the case where directory path meets prescribed form, be otherwise judged as illegal.Specifically judgment method is
Technology commonly used in the art, in this, it will not go into details.
